Abstract: Addressing the unpredictability of tunnel fire accidents, this paper presented a dynamic quantification approach to ascertain the probabilistic metrics of traffic tunnel fires, complemented by a statistical case study analysis. Causal analysis of tunnel fires identified vehicles as the principal disaster-inducing factors. Taking into account the conditions of the vehicles and the environmental impact within the tunnel, the individual fire frequency for each vehicle type was corrected. Then synthesizing above modification value with the number of vehicles inside the tunnel could obtain the tunnel's vehicle fire probability, which was amalgamated with the statistical probabilities of other incendiary events to construct a probabilistic quantification model for tunnel fires. Two empirical case studies analysis were conducted on a specific tunnel, resulting in the fire probability distribution within a 24-hour period. This achieved a dynamic quantification of the potential for fire occurrence, which provided a basis for real-time risk identification and accident prevention of tunnel fires.
